STOP-VALVE FOR WATER AND GAS.

SPECIFICATION forming part of Letters Patent No. 266,664, dated October31, 1882,

Application filed January '16, 1882. (No model.)

To all whom it may concern Be it known that I, FREDERICK 0. VINEY, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulPlug Stop-Valve for Water and Gas Mains, of which the following is aspecitication.

My invention relates to improvements in four-way plug stop-valves forwater and gas mains, the distinguishing features of which are that theplug is square, slightly tapering toward its lower end. The sides areprovided with adjustable hard metal plates that come in contact with thesoft-metal or wood seats around the several openings of bell-nozzles;and the objects of my invention are, first, to provide a square plug,slightly tapering toward its lower end, which forms its own seat andavoids the necessity of fitting, grinding, and scraping; secondly, toprovide each side with adjustable hard-metal plates that may be removedfor repairs, thus making a simple, durable, and cheap valve. The smallamount of valve-seat surface exposed to the sides of the plug and itstaper prevents the plug from getting fast. It is always free, andstartswithout trouble. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure 1 is a sideelevation. Fig. 2 is a vertical longitudinal section atline 0c 00, Fig.3, embodying my invention. Fig. 3 is a plan of valve with cup removed.Fig. 4 is a plan of square plug. Fig. 5 is a central section of plug aty y, Fig. 4.

Similar letters refer to similar parts throughout the several views.

The case A has four bell-nozzles, I J K L, and a fire-plug connection,M, below. The cover B is secured to case A at the top with the necessarybolts, and is provided with stuffing-box F and Gr, necessary to preventleakage. Valve-stem E passes through stuflingbox and nut, and isattached to square plug by means of a head or stem, E, which fits slot Hin the upper large end of plug 0. Thusit will be seen that, the nutbeing part of the cover 13, the stem E moves vertically with plug 0,enabling me to make a solid plug. In the presentinstance I show aspider, 1 on valve-stem E; but in practice, when the valve is underground, I square the end and have a socket-wrench to turn the valve-stemfor raising and lowering the valve for the purpose of opening orshutting off the supply. The valve-seats of the several bell-connectionsI J K L of easing A, Fig. 3, are formed by making dovetailed circularcavities N as much larger than the bore of the bell-connections to allowsufficient surface to prevent leakage. These cavities N are filled withsoft metal or wood to correspond with the taper ot' the square plug 0.The manner of constructing the square plug-valve O is shown in Figs. 2,4, and 5. The oblong slot II is cored in top of the large end of plug 0to admit freely the head of valve-stem E, and tapering dovetailed slotscored in each side of the plug, in which liard'metal plates D are forcedand pinned. It is then put on a planer or shaping-machine, and trued upthe desired taper, when it is ready to be placed in the casing.

I place this valve at the street-crossing where two lines of water orgas mains intersect each other, and connect nozzle M to one or morefire-plugs placed at the corners of the street when used on water-mains,and blanked off when used for gas. It will be seen that the bottom 0 ofvalve-body A is on line with the bottom of bell-opening M, so that allsediment which collects in receptacle beneath plug-valve C may be blownoil through fire-plug nozzle M, keeping valve always free from dirt.

I am aware that valves have been made taper or wedge shape operatingagainst flat surfaces. I therefore do not claim a valve for surfacecocks and faucets; but

\Vhat I do claim as my invention and desire to secure by Letters Patent,is

1. A tapering valve-plug having several sides, and thevertically-i'novable valve-stem fitted to the head of said valve-plug,in combination with valve-seats N, formed of circular cavities filledwith soft metal to correspond with the tapered sides of said plug, andoutlets or passages covered by said valve plug and corresponding innumber and loeaconstructed to fit the tapering shape of the tion withthe sides thereof, substanti-illy as set sides of said valve-plug,substantially as set 10 forth. forth.

2. A verticallymovable valve-stem and w T 5 thet'apering valve-plughaving several sides, FhEDERK/K CHARLES VINEX' each side covering aseparate passage or out- Witnesses: Yet, in combination with removablehard-metal LINN SLAYMAKER, plates fitted to said sides, and valve-seatsN, iICHARD J. LEMON.
